DYEING APPARATUS.

' applicatien filed September 3, 1921. Serial 110,498,198.

To allwhomz't'may concern:

Be it known thatI, JOHN D. 'HnNo'N, a citizen of the United States,residing at Philadelphia, in the county of Phlladelphia and State ofPennsylvania, have invented new and useful Improvements in a DyeingApparatus, of which the following is a specification.

My invention relates to new and useful improvements in a dyeingapparatus, and

has for its object to construct such a device that the timerequired todyeyarns in dyeing tubs or vats of the propeller type now in general usewill be considerably shortened as'the dyeing liquid will be directedtoward thematerial being dyed rather than permit it to flow about thematerial in the lines of least resistance. a

Another object of the invention "18 to utili-zethedyeing. tubsor vats'now in use by applying mysimproved deflectors or baffles I within ,thedyeing compartment thereby giving a better distribution to the dyeingliquid and giving a more even-distribution of the color to the yarn orother material being dyed. g I

A further. object of the invention is to provide an upper and lowergrating of unique construction, which will assist in deflecting thedyeing liquid aswell as checking the flow thereof thereby preventing theyarn from becoming entangled or packing against the different parts ofthe dyeing apparatus. I A still further object of the invention is toprovide an improved construction ofdye .vat cover and yarn stick supportthe latter being detachably, connectedwith the former so as to, betransported with the cover durlng thetime the yarn is being placed in orremoved from the dyeing apparatus. v

' With these ends in view, this invention consists in the details ofconstruction and combination of, elements hereinafter 'set forth andthen specifically designated by the claims. r I

In order that thoseskilled in-the art to which this inventionappertains, mayunderstand how to makeand use-the same, I will describeits construction in detail referring lby numerals'to the accompanyingdrawings F ig. 2, is a side elevation thereof with the nearslde wallremoved and the deflectors or b'a'flies as well as certain of the otherelements being shown in section to clearly illustrate the construction.v

F 1g. 3, is an end view thereof with the end wall and partition removedand the baffles or deflectors illustrated in section.

' ig. 4, is an end view" of the vat cover removed therefrom. V

Fig. 5, is a similar view of the yarn stick support disconnected fromthe cover.

In carrying out my invention ashere embodied, 2 represents the ordinarywell knownv above said partition. In the circulating compartment 4 islocated suitable propel ling or circulating means 8, here shown as apropeller which is mounted in any suitable manner and driven by anydesirable means. ,Across the lower part of the compartment 3 anda'sliort'dlstance above the bottom of the dye vat or the tub arearrangedor located a plurality of series of transverse .horizontalrods 9forming a grating through which the dyeing liquidpasses and said gratingacts as a check to the flow of the dyeing liquid as well as deflectingthe same so asto cause it to have a number of cross currents therebycompelling it to flow into and through the'yarn in the dyeingcompartmentrather than permit it to flow upward between the skeins yarnor along the lines of least resistance.-

' Intermediate the height of the dyeing compartment 3 and around all theboundary walls thereof, as for instance the side walls and one end wallof the vat andthe partition 5 is arranged or locateda deflector or.baflie 1O in the form of a protuberance or rib projecting from theaforementioned walls and this baffle or deflector 1s semi-oval in crosssection as plainly shown in Figs. 2

and 3. This baffle or deflector may be constructed of any suitablematerial in any desirable or well known-manner but is preferably-formedfrom a number of wooden strips, boards or planks properly shaped andsuitably attached to the different Walls of the vat. i

On top of the dye vat or tubismounted a suitable cover 11 same andhaving eye bolts13 connected therewith whereby av suitableqhoistingapparatus maybe attached for lifting the cover, when the'same is beingplaced onor removed from the dye vat. Depending from two op p'osite sideedges of the cover are the side flanges 14v having longitudinalhorizontal slots15 there'through for the passage of the dyeingliquid aswill be llelflntftel' deQ scribedand below these slots are mounted aplurality'or series of rodsilo thereby-plfoducing the upper gratin whichis used for the same purpose as the fower grating 9 and has the sameactionon the liquid as said gratingiQ. As the rods 16'forn 1ing, theupperv grating aremountedf or setin'the side flangesl said grating isremoved from the-dye vat each timelthfe cover is displaced and inpractice said flangesfle are each formed by two'spaced members withsuitable spacing blocks and arranged between their adj a'cent edgesethespacingof, said elements forming the aforementioned slots.

7 "The numeral 1 8":denotes" the yarn stick. support and consists ofmembers 19 in the same spaced relation to each other as are thedepending flangcsi i of the dye vatcover, the, said dye stick supportadapted to be detachably connected withithe saidflanges W r s. i f upparmay et anspq from place to place with thecover andhung within the vatwhen the cover is in: place thereon and although it will beohvious thflt any suitable means be utilized for deftachably connectingfit e supportto., said edge of each of the s on members 1 9 are formed a plurality onotches 231130 re- "ceive the ends of the yarn sticksiii from whichl theskeins of yarn'are hung, 'in the ordinary, manner and the'open ends ofsaid notches, are closechby the coaction of the flangesi i withthemembers 19 thus fpreventing the accidental displac'ement, oi the yarnsticks. a i V 1 In pra'ct'ce the dyeing liquid within the dye vat br tubsh ouldhc caused to, circulate very slowly first ingonedirection andthen ii the other, and when circulating in the direction'which carrlesit from the'compartto which are fastened the cross beams 12 forstrengthening the support may be set 1 e e e permit the yarns to ry, butwhilethe yarn oss pieces 22"fixedte the.

ment/i to the compartment 3 underneath of the partition 5 said liquidwill pass through the grating formed by the bars 9 at the lower portionf hescompar mflnw and be broken up into a number of cross currentsflowin upwardly through the compartment 3 an that portion of the liquidwhich would naturally follow-the enclosing walls of the compartment. 3,because of these points there is practically no' resistanceto the flow,of

liquid "but as thesestreams of'liquid reach the bafiie or deflector 10it will be deflected j inivardand causedto flow through the yarn thusmpre evenly distributing the color and] producing a better and moreuniform dyeing as well as facilitating and expediting the dyeingoperation and as the liquidpasses on up through the material" beIng'-dyed-it ow through the slots 15 and will finally then aroundthe flanges14; as Well as over the upper end of the, partition 5 into thecirculating chamber 4. When the flow-oi the liquid-is reversed it'will'flow overt-he partition into the chamber 3 andfalso between theflanges14- and the side walls of the vat and then through the, slots 15into said chamber 3 where it w illbe checked and reflectedb y the uppergrating fiand that portion flowing downward within the chamber 3adjacentfithe enclosing walls and. will be finally passing beneath thepartition to the chamben i.

This deflecting of the dyeing-{liquid i as it passes through thecompartment 3 makes it unnecessary to circulatethe liquid at a highspeedthereby eliminating "or" reducing t'o' a minimum the possibilityofthe yarnsbeing tangled or caused to double up 01"- pack onthegratings, I I V As" the; yarn stick support is I detachable from thecoverofthedyeing-apparatus said on suitable holders to is beingremiovedor placed upon the sticks thereby saving considerable "time inthe ing the time one "batch of yarn is being operation of'tl'iedyeingeapparatusforpdur-n placedupon or removed from the sticksan- Wother batch may be submewed in the dyeing and supporter therefor:

Of course I do not wish liquid by the use of additional yarn sticks l tobe liniited te the exact details of constr'uotion'ias herein shown asthese may be varied within. the

limits of the appended claims withoutde- I parting from the spiritjof myinvention Having thus fully described my invention,
